ADJUSTABLE MOLD FOR CEMENT TROUGHS.

SPECIFICATION forming part of Letters Patent No. 644,397, dated February or, 1900.

Application filed September 28,1899. Serial No. 731,905. (No model.)

To aZZ whom it may concern:

Be it known that I, JEREMIAH BOLTON, a citizen of the United States, residing at Leslie, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Adjustable Molds for Cement Troughs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in molds for making cement water-troughs for stock; and its object is to provide an adjustable mold whereby troughs of various sizes may be readily made, stay-bolts set in the trough, and the device provided with certain new and useful features hereinafter more fully described, and particularly pointed out in the claims.

My invention consists, essentially, in providing the device with a sectional inner part, whereby its inner dimensions may be varied at pleasure, and an outer part having changeable and adj ustable end walls and in certain details of construction, as will more fully appear by reference to the accompanying drawings, in Which- Figure 1 is a plan view of a device embodying my invention; Fig. 2, a side elevation of the same with parts broken away to show the construction, and Fig. 3 a transverse vertical section of the same on the line 3 3 of Figs. 1 and 2.

Like letters refer to like parts in all of'the figures.

A represents the side walls of the mold, made of planks or other suitable material and of any suitable dimensions. Between these side walls and connecting the same are the adjustable end walls B, which are of the same width as the side walls and of any convenient length. These end walls abut against the side walls at right angles thereto and are provided with openings 0, in which openings are removably inserted pins 0', fixedin clamp- These bars embrace the side walls A A and are drawn together against the upper and lower edges thereof by clamping-bolts E E, detachably engaging slots in the ends of the bars.

The inner part of the mold consists of a series of transversely-convex side sections F, having at each end a head F. These sections are arranged in opposing series at each side and connected by bolts I to form the required length. One or both of the end walls B may be adjustable and arranged at a suitable distance apart to afford the proper spaces between the parts of the mold at the ends. The opposing sections are separated throughout by detached pieces of planks G and G, which planks may be varied in width to vary the space between the side walls A and the convex sections F, and the end walls may be removed and others of different width in serted to change the total width of the mold. These sections F are held in place by removable bolts H, and blocks K are placed between the sections F and side walls A to keep the sections in proper adjustment. When the mold is nearly full, these bolts and blocks are removed and the balance of the cement placed in the mold. To place a permanent stay bolt M in the trough, opposite indentations L are provided in the upper edges of the opposite sections F, and the stay-bolt M is provided with an anchor-plate M at each end, and these plates are embedded in the cement. When the end sections have been removed and the planks G and G taken out by moving the bottom of one of the indented sections F against the bottom of the opposite section, the upper edge of the former will slide down enough to pass under the bolt M, and this section can then be moved endwise and taken out, leaving the bolt M in place. Strips J are temporarily attached to the end heads F to prevent crowding in the end planks G. The pins 0 prevent the ends from being pushed out from between the clamping-bars, and by slacking the bolts E the ends B can be adjusted longitudinally of the sides. By removing the bolts E the side walls A and ends 13 may be separated and removed from the trough.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of side walls, an end wall adjustable longitudinally of the side walls, and an inner mold having transverselydivided and detachable sections to vary the length of the mold, and planks between the said sections to Vary the width of the mold, substantially as described.

, 2. The combination of side walls, an end wall abutting against the side walls, clamping-bars embracing the side walls and connected to the end walls, and detachable bolts engaging the clamping-bars, substantially as described.

8. The combination of adjnstably-conneeted side walls and end walls, and an inner mold composed of convex sections having heads attached in series bybolts, and detached planks of variable widths between the opposing sections, substantially as described. I 5

planks between the opposing sections, substantially as described.

6. The combination of outer side and end walls, convex sections having heads and detachably connected, detached planks between the opposing sections, bolts passing through the side walls and supporting the opposing sections, and blocks between the side walls and sections, substantially as described.

7. The combination of side walls, end Walls abutting against the side walls, clampingbars embracing the side walls and end walls, pins detachably connecting the bars and end walls, detachable bolts connecting the clamping-bars, convex sections having heads and connected by bolts and also having opposing indentations in the upper edge, detached planks between the opposing sections and heads, bolts passing through the side walls and also through the sections, and blocks between the side walls and sections, substantially as described.

In testimony whereof I aliix my signature in presence of two witnesses.

JEREMIAH BOLTON.
